Traffic slowed to a crawl Wednesday afternoon after a chain-reaction crash on the Truck Route near the N.M. 4 intersection. A late model Subaru rear-ended a gray Nissan Maxima in front of it, causing that vehicle to hit a Nissan White station wagon, which slowed because a vehicle in front of it was turning. The only injury reported was from the driver of the Subaru, who police said is probably going to be cited for following too close.
